The University of Hawaii's ALOHA ("A Long-term Oligotrophic Habitat Assessment") Cabled Observatory (ACO) is located 100 km north of the island of Oahu, Hawaii (22 45'N, 158W) in the North Pacific Ocean. It provides real-time oceanographic observations from a depth of about 4,800 m via a submarine fiber optic cable that comes ashore at Makaha on Oahu. This data set provides the most recent 48 hours of measurements of ocean pressure at the ACO from a Bottom Pressure Recorder (BPR).
